Question

The probability that an airplane engine will fail in a transcontinental flight is 0.002. Assuming that engine failures are independent of each other, what is the probability that on a certain transcontinental flight, a six-engine plane will experience:
(a) Exactly one engine failure? (Round your answer to five decimal places.)
Correct: Your answer is correct.

(b) Exactly two engine failures? (Round your answer to six decimal places.)
I NEED THIS ONE

(c) More than two engine failures? (Note: In this event, the airplane will crash. Round your answer to nine decimal places.)

Answer 1

I need B

Answer 2

Ok, let's see. 0.002 ^ 2 = 0.000004

Answer 3

Do you also need C?

Answer 4

no I have C

Answer 5

is B that easy?

Answer 6

Your answer to B is wrong @D35TR0Y3R .
The answer is (0.002)^2 * (0.998)^4 * 6C2 =
(0.002)^2 * (0.998)^4 * 15
= .00006

Answer 7

That 6C2 is combinations of 6 things taken 2 at a time..or 6! / (6-2)! 2!

Answer 8

Are you sure you got A correct?
.002 * .998^5 * 6 = .01188

Answer 9

let me check

Answer 10

yes
